Hi Martin,
Thanks for your comments.
I was trying to cobble together info from various sources on the net
by brave folks who attempted the Lucene-Cake bastardisation route
before me.
I agree with the 'set_include_path' It was the latest attempt after a
long series of attempts to get it to work. It returned the least
number of errors and, at that point in time, it was going to do for
me. However, it kept cropping up when smarter people than me write
about Zend and Cake (as either set_include_path or ini_set
('include_path') [1][2]
Jonathan Snook actually added it to his core.php :O [3]
As for assigning the controller to the $controller, I was, once again,
following the wisdom of others. Golding's book he stated:
"[U]se the startup() function to instantiate the controller object.
Then all functions in
the controller can use $this->controller to access anything in the
parent controller.
function startup(&$controller)
{
$this->controller = $controller;
}
"[4]
Doing DB calls to the controller. You're right, I have no idea what I
was thinking. It was a brain-fart that stuck and stayed, I believe
(not a pretty metaphor, sorry).
Finally I totally agree with you on the caching. It is on the cards. I
was just trying to get the easy stuff working first. (ha ha ha).
Also I realise that a lot of these sources were written when Cake was
still a baby and things have changed by leaps and bounds since.
Moreover, I am (obviously) new to all this and may have picked up the
wrong end of every stick while reading articles on this topic. What I
am trying to say is that I am in no way suggesting that these articles
I sited here are wrong...just wrong to me :)
Thanks again, Martin, for your time.
